About The Position

Imagine what you can do here. Apple is a place where extraordinary people gather to do their lives best work. Together we create products and experiences people once couldn't have imagined, and now, can't imagine living without. It's the diversity of those people and their ideas that inspires the innovation that runs through everything we do. APPLE INC has the following available in Cupertino, California and various unanticipated locations throughout the USA. Tuning SoC memory performance state controllers, and proposing improved control and observability mechanisms, for unreleased silicon products. Driving accurate performance and power projection of complex, realistic workloads on a full-system simulator. Planning and carrying out architecture studies which are highly visible and critical to driving architecture decisions that maximize the performance and energy efficiency of future Apple SOCs. Collaborating with teams at many layers of the hardware/software stack. Develop and use a deep understanding of the operation of current and planned Apple products, from application software to system software to SOC architecture and microarchitecture. Disseminating multi-functional, system-level understanding across the silicon design organization. Writing and using tools to perform detailed, repeatable analysis of simulated and measured data. Clearly documenting and communicating findings from device capture and simulation results throughout the company to enable data-driven SOC and product-level decision-making. Participating in architecture definition for future SOCs and tuning for existing SOCs and software based on findings.

Requirements

Bachelor’s degree or foreign equivalent in Computer Engineering or a related field.
Developing automated flows in Python for workload capture on internal prototype devices and OS builds, as well as for automated large-scale postprocessing, analysis, and visualization of hardware and software trace data.
Using Pandas, Matplotlib, Seaborn, and scikit-learn Python packages for data analysis and visualization.
Understanding and making quick prototyping-related or production-worthy changes to large software projects
Designing, carrying out, and presenting results from experiments having to do with collecting performance and power data on current silicon, and forecasting workload behavior, performance, and power on future silicon.
Building, using, and evangelizing the use of automated, robust testing flows for continuous integration, continuous regression testing of build-to-build software behavior changes.
Using data analytics tools Tableau and Splunk.
Writing simple internal-only drivers for new pieces of hardware and driving improvements to SoC-level tracing and debug tools using understanding of VLSI, digital logic, and system software concepts like memory-mapped I/O and interrupts.
